…as far as I know…
The health condition in the Sami population of Sweden
“Early contacts with the western society brought infectious diseases such as smallpox and tuberculosis, while western influence during the last five decades have had more profound effects on the lifestyle causing an increase of lifestyle related western diseases such as cancer, diabetes, stroke, obesity and hypertension.”
“Compared to other native populations, the prevalence of infectious diseases appears to be low among the Sami.” “Even though the knowledge is quite incomplete, the Sami does not seem to suffer from infectious diseases more than Swedes in general”.
